Question

Shirley has enrolled for violin classes. She puts in a total of 14 hours of practice

Answer 1

Step-by-step explanation:

1 week = 7 days

given 7 days = 14 hours of practice

and let x be the number of hours spent on practicing and y the number of days.

from the above expression we can have the equation,

$y = \frac{x}{2}$

using the equation when y = 10,

$\frac{x}{2} = 10 \\ x = 2(10) \\ = 20$
